Also you forgot to consider SMTs which will have a constant way of injecting new money into the platform
There is no guarantee these SMTs will be worth anything as much as Steem or higher. Steem itself has dropped rank on CMC from #3 to #33 and it needs a lot of traction to get to the top 20.
I'm optimistic about SMTs adding value to the network and growth in Steem value. But i'm also realistic about falling prices and influence in the short term owing to large stake holders in competition with each other on who can have the largest piece of the pie around here.
